A car that won’t start can be frustrating, often pointing to issues within the car ignition system. From faulty spark plugs to failing ignition coils, this article explains common ignition-related problems and how to address them with quality parts from MAPMS.

Common Ignition System Issues

• Faulty Spark Plugs: Worn or fouled plugs prevent proper combustion, leading to starting failures.

• Bad Ignition Coils: Fail to deliver sufficient voltage to spark plugs, disrupting ignition.

• Defective Ignition Switch: Prevents power from reaching the starter, halting the start-up process.

Troubleshooting Steps

1. Check Spark Plugs: Inspect for wear or damage, such as carbon deposits or electrode erosion, and replace if needed.

2. Test Ignition Coils: Use a multimeter to verify functionality, checking for proper voltage output.
